Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the CLN3 gene is commonly pathogenic or not. These statistics are base on transcript: NM_001042432.2. Only rare variants are included in the table.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: Involved in microtubule-dependent, anterograde transport of late endosomes and lysosomes. {ECO:0000269|PubMed:22261744}.
• Disease: DISEASE: Ceroid lipofuscinosis, neuronal, 3 (CLN3) [MIM:204200]: A form of neuronal ceroid lipofuscinosis. Neuronal ceroid lipofuscinoses are progressive neurodegenerative, lysosomal storage diseases characterized by intracellular accumulation of autofluorescent liposomal material, and clinically by seizures, dementia, visual loss, and/or cerebral atrophy. The hallmark of CLN3 is the ultrastructural pattern of lipopigment with a fingerprint profile, which can have 3 different appearances: pure within a lysosomal residual body; in conjunction with curvilinear or rectilinear profiles; and as a small component within large membrane-bound lysosomal vacuoles. The combination of fingerprint profiles within lysosomal vacuoles is a regular feature of blood lymphocytes from patients with neuronal ceroid lipofuscinosis type 3. {ECO:0000269|PubMed:21990111, ECO:0000269|PubMed:22261744, ECO:0000269|PubMed:9311735, ECO:0000269|PubMed:9490299}.
